Another thought… perhaps when you press the sealing bar, there is too much pressure and the snorkel tip is getting trapped. It might help to seal, release the arm, then re-seal again just a few millimeters further back as “insurance.”
We also suggest you can press the closed end against the inside wall of the fridge when you put it on the rack. Holding it there just the few days it takes for the bond to form, then moving it to leave room for air to flow has worked. As I think you understand, once the majority of the DrybagSteak has bonded with the surface of the meat, the process is well on its way. It is not a “vacuum” you need so much as simply really, really good contact.
Let’s hope we can find success for you!
